Modern Precision to 62RI conversion project

Ok, I'm trying to limit the number of basses I have...I've got a 4 string 62RI P bass that sounds marvelous, but is a 4 string and doesn't like high tension strings like I like...and a new American Std P5, which plays like a dream, but has significantly more high end to the sound--and just isn't as tonally "perfect" in a mix, compared with the 62RI.

Same woods--Alder, rosewood neck. Finish is different, but I would think the 62's nitro would let MORe high end resonate...not less...

Bridge is different, but the new one can at least be strung through the body OR through the bridge. I've tried both.

So, electronics. Pickups: totally different. I've been told by the dealer that Fender's Custom Shop will not sell custom parts, even though you can buy the 62RI PU retail, they would not be willing to wind a 5 string version for me. Spoke to Lindy Fralin--he said he's not tooled up to wind a 5 string P PU and wasn't sure how different his was from Fender's stock winding. It's been suggested that I call Duncan's custom shop, who probably can get the specs of the 62 PU from Fender and custom wind one. Maybe I will.

But, then there's the tone cap. Maybe some of you electronics gurus can sort this out for me: the 62 has a large orange plastic (mylar?) cap with the following on it:

ic
.1k
250S

and the Amercian Std 5 has a cheapy ceramic cap that reads:

ic
503z (or 5032 maybe)

I'd like to get those to match as best before betting into the PU custom winding, since they do sound so similar when you roll a LOT of highs out of the modern one on the board.

Ideas? Suggestions?
 
I can't help you with the cap, but another thing you might double-check (if you haven't already) is the pot values for the volume and tone controls. The way I understand it, if the P5 pots have higher resistance (500K vs. 250K, for instance), that might account for a bit of the added brightness.

Sounds like your capacitor might be [Invalid or Expired Link Removed]? It's hard for me to tell, but I'll guess from the labeling on that cap in your 62RI that it's a .1µF capacitor.

As for the pickup, 5 string P pickups aren't the most popular production model out there. Your desire to closely emulate that 62RI throws out some stock pickups like one TBer says they exist and one TBer says they exist that definitely aren't aiming for an emulation of vintage Fender tone.

Take a look at the Nordstrand NP5. The stated design goal on that one is vintage P, just with 5 strings. Might be 100% what you're looking for! :)

Another possibility is a 5 string P model supposedly produced by Bill Lawrence. I can't find it on their site at all, but Invalid Link Removed.
 
Tell me more about this. I've been considering an NP5 myself.

Anyone out there have sound clips?

I may just start out with a 500k pot and a 0.1 micro farad cap. I figured that would leave me with the option for a nice, bright high end that I could roll off for a thumpier sound. Any thoughts?
 
I'm sure the Nordstrand is great, but you should call Seymour Duncan too. I believe Mike Lull uses custom made Duncans in his P5, which I think sounds similar to the Fender '62 RI. I haven't played them side-by-side, but they've produced similar impressions when I have played them. Now that Fender makes its own P5, Duncan will probably offer a production model soon.
 
FYI. No on the Duncans. They wanted to rewind the current pickup...they don't have a cover--same issue Lindy Fralin had, and frankly, if I'm paying someone to custom wind me a PU, he's gonna get the biz from me for being a good guy and doing an AMAZING job on Strat PUs.

Current thought is buying one of these:

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ssPageName=STRK:MEWAX:IT&item=120266355342

--risk the $25 that the cover fits. If it gets here and it's the right dimensions, send it off to Lindy to wind.

Anyone know anything about these PUs? Any reason this might be a bad idea?
